Do you matter?

Ever get so tired of a day in and day out on a job where you feel life is just going by and there you sit?  Looking around at others in the office then it dawns on you that you are the oldest one in that office and all those in charge are in their 20's or 30's.  How did this happen when did the pathways go astray?  Driving home not sure how you get there because the mind is still trying to figure it all out and wanting to find a way to feel needed or even important in some way.  Among folding letters, stuffing envelopes answering the phones thinking is this it, is this all there is to ones self and as the day turns to night the last thing you think of as the eyes close is....do you matter?
